In order to scan DVB-C with MythTV, you need to give it an initial transponder in a tuned scan. The data you need to enter is: frequency, polarity, symbol rate and modulation. The information can be obtained from your operator. (Should it not be easily available it can also be obtained from an [http://linuxtv.org/hg/dvb-apps/file/default/util/scan/dvb-c initial tuning file] or a channels.conf for your location.)
